Problems solved by technology

[0003] In current life, magnetic wireless charging is more and more widely used, but because the magnets around the magnetic wireless charging will affect the magnetic field of the coil, resulting in low wireless charging efficiency, or even charging, so the charging coil in the magnetic wireless charging still needs to be developed. for further improvement

Embodiment 1

[0023] see Figures 1 to 2 , In the embodiment of the present invention, a magnetic suction wireless charging coil includes a bottom case 6 with a circular arc structure, the top of the bottom case 6 is fixedly installed with an upper cover plate 13, and the upper cover plate 13 and the bottom case 6 are connected A fixed cavity is formed between them, the fixed cavity contains a coil 1, the coil 1 is installed in the circular groove opened on the top of the fixed gasket 3, and the fixed gasket 3 is installed on the side of the fixed cavity close to the bottom case 6, A magnetic isolation component 4 is installed around the coil 1, a non-magnetic induction plate 5 is fixedly installed on the outer side of the magnetic isolation component 4, and a number of fan-shaped heat dissipation structures 8 are opened between the coil 1 and the side surface of the bottom case 6, One side of the coil 1 is connected to a lead 7 which passes through the interior of the bottom case 6 and ext...

Embodiment 2

[0025] see Figure 1-2 , the difference between this embodiment and Embodiment 1 is:

[0026] In this embodiment, a plurality of positioning bolts 14 of the same structure are installed on the upper cover plate 13 , and the positioning bolts 14 penetrate through the interior of the upper cover plate 13 in the radial direction and are installed in the bolt holes 2 opened on the fixing gasket 3 , the position of the upper cover plate 13 can be fixed through the bolt holes 2, so that the whole device is more stable; the edge position of the bottom case 6 away from the lead 7 side is installed with a hinge assembly 17, and the other end of the hinge assembly 17 is fixedly installed on the bottom case. 6 port.

[0027] In this embodiment, an encapsulation layer 16 with a circular structure is also installed between the bottom case 6 and the upper cover plate 13 , and the inner side of the encapsulation layer 16 is close to the side outer wall of the bottom case 6 , and the presenc...

Abstract

The invention relates to the technical field of charging coils, in particular to a magnetic wireless charging coil which comprises a bottom shell of an arc-shaped structure, an upper cover plate is fixedly installed on the top of the bottom shell, a fixing cavity is formed between the upper cover plate and the bottom shell, a coil is contained in the fixing cavity, and the coil is installed in a circular groove formed in the top of a fixing gasket. The fixing gasket is installed on the side, close to the bottom shell, in the fixing cavity, a magnetic isolation assembly is installed around the coil, a non-magnetic-induction plate is fixedly installed on the outer side of the magnetic isolation assembly, a plurality of heat dissipation structures of a fan-shaped structure are arranged between the coil and the side face of the bottom shell, one side of the coil is connected with a lead, and the other side of the coil is connected with the lead. The lead penetrates through the interior of the bottom shell and extends to the outer side of the device; the magnetic isolation assembly can effectively isolate a magnetic field generated by an external permanent magnet, a transformer, a motor, a coil, a cable and the like, so that the coil transmission magnetic field stability and the magnetic attraction wireless charging efficiency are improved, and certain economic benefits are obtained.

Description

technical field [0001] The invention relates to the field of technical charging coils, in particular to a magnetic wireless charging coil. Background technique [0002] With the continuous improvement of the requirements for power supply quality, safety, reliability, convenience, immediacy, special occasions, and special geographical environments of electrical equipment, the contact type power transmission method is increasingly unable to meet the actual needs. Wireless charging technology It is a special power supply method that does not require a power cord, relies on electromagnetic wave propagation, and then converts electromagnetic wave energy into electrical energy, and finally realizes wireless charging. [0003] At present, magnetic wireless charging is more and more widely used in life, but because the magnets around the magnetic wireless charging will affect the magnetic field of the coil, the wireless charging efficiency will become lower, or even charging will no...
